Question

a horse is tethered to one corner of square plot of side 42m,by a rope 35m long, find 1)what area can it gaze. 2)what area will be left ungrazed?

Answer 1

Area of grazing = 1/4 of area of circle with radius =35

= 1/4 x pi x r x r
= 1/4 x 22/ 7 x 35 x35
= 962.50 sq m


Area left ungrazed = Area of sq - previous answer
= 42 x 42 - 962.50
=801.50 sq m
